[0040] Example 1

[0041] like Figures 1-5 As shown, a safety isolation guardrail for coal mine electromechanical equipment includes a barrier fence mechanism 2. The barrier fence mechanism 2 includes a first fixed guardrail symmetrically arranged on the front and rear sides. The first fixed guardrail is a fixed structure. Specifically, the main structure of the first fixed guardrail includes a frame-shaped frame part 231, and a plurality of horizontally arranged guardrail crossbars 23 are fixedly connected inside the frame-shaped frame part 231.

[0042] Meanwhile, a logistics channel barrier 24 is fixedly connected between the left ends of the first fixed barrier, and the logistics channel barrier 24 can be adjusted to form an open logistics channel.

[0043] Specifically, by designing the logistics channel railing 24 to be movable, it facilitates the transportation of large trapezoidal electromechanical equipment when it is necessary to disassemble the equipment during operation, such as during maintenance.

[0044] Specifically, the logistics channel barrier 24 includes two fixed crossbeams 241 welded and fixed between the left ends of the frame portion 231. Specifically, the fixed crossbeams 241 are fixed between the upper and lower ends of the frame portion 231, respectively.

[0045] Meanwhile, a pair of spaced longitudinal rods 242 are fixedly connected between the fixed crossbeams 241, with the longitudinal rods 242 approaching the frame portion 231. That is, the spacing between the longitudinal rods 242 is relatively large, which facilitates disassembly and transportation of the equipment and leaves sufficient clearance.

[0046] Meanwhile, several sliding crossbeams 243 are slidably connected between the longitudinal rods 231 and are spaced apart vertically. Several support nuts 2431 are threadedly connected to the longitudinal rods 242 and are respectively supported at the bottom of the sliding crossbeams 243.

[0047] During operation, when it is necessary to transport and disassemble equipment, all sliding crossbeams 243 are slid upwards until they abut against each other (and press against the fixed crossbeam 241 at the upper position), thereby releasing the logistics channel (the width of the channel is the distance between the longitudinal bars 242 on both sides, and the height is the distance between the bottom sliding crossbeam 243 and the bottom fixed crossbeam). Equipment that is easily disassembled can pass through the flow channel railing in this way.

[0048] A pedestrian passage barrier is fixedly connected between the right ends of the first fixed barrier, and a pedestrian passage door is hinged on the pedestrian passage barrier.

[0049] Specifically, the pedestrian access barrier includes several barrier bars 21 welded between the right ends of the frame section 231 (the barrier bars 21 are spaced vertically). Installation openings are made between the barrier bars 21 (the installation openings are formed by cutting each barrier bar 21), and a passageway door 22 is hinged into each installation opening. Similar to existing methods, a U-shaped door frame is welded into the installation opening, and, also similar to existing methods, the passageway door is hinged to the door frame. This allows personnel to enter the barrier mechanism 2 by opening the passageway door.

[0050] Example 2

[0051] like Figures 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, a fixed mesh frame plate 3 is fixedly connected to the outer side of the first fixed railing. The stability of the entire railing structure is increased by fixing the mesh frame plate 3. Specifically, the fixed mesh frame plate 3 is a perforated board material of wood or plastic structure, which is fixed to the first fixed railing by a fixing method such as bolts to provide impact resistance.

[0052] The above-mentioned logistics passage fence 24 is hingedly provided with a hingedly movable net rack plate 5. Similarly, the hingedly movable net rack plate 5 is used to increase the anti-collision capability of the logistics passage fence 24. Specifically, the safety isolation fence for coal mine mechanical and electrical equipment further comprises a top blocking 1 fixedly connected between the top portions of the blocking fence mechanism 2 (the bottom of the top blocking 1 is fixedly installed on the top portion of the frame portion 231 through a plurality of installation rods).

[0053] Hingedly movable net rack plates 5 are hingedly connected to the hinged seats on both sides (left ends of the front and rear side walls) of the top blocking 1. Long installation openings 51 are formed in the top portions of the hingedly movable net rack plates 5. A support rod structure is hingedly connected to the outer sides of the opening portions of the long installation openings 51.

[0054] Specifically, the support rod structure comprises a support rod 6 hingedly connected to the long installation openings 51 (the lower end of the support rod 6 is hingedly connected to the long installation openings 51 through a pin shaft, which is the same as the existing mode). An adjustable support rod 61 with adjustable length is threadedly connected to the support rod 6. Specifically, a threaded cavity with a certain length is formed in the support rod 6. The adjustable support rod 61 is threadedly connected in the threaded cavity. When it is necessary to turn over the hingedly movable net rack plate 5 to facilitate the opening of the logistics passage and the transportation of the equipment to be disassembled, the support rod 6 and the hingedly movable net rack plate 5 are turned over. After the support rod 6 is turned over, the support rod 6 is kept vertical. Then, the adjustable support rod 61 is rotated until the adjustable support rod 61 is supported on the ground.

[0055] Then, the operator transports the disassembled equipment. After the transportation is completed, the hingedly movable net rack plate 5 is reset. At the same time, the support rod 6 is rotated until the support rod 6 is accommodated in the long installation opening 51 again. In order to keep the support rod 6 positioned, a resilient protrusion 511 is fixedly connected to the inner side wall of the long installation opening 51. The support rod 6 is positioned through the resilient protrusion 511. Specifically, the support rod 6 is kept positioned under the elastic extrusion of the resilient protrusion 511.

[0056] The safety isolation fence for coal mine mechanical and electrical equipment further comprises a plurality of static electricity releasing belts 4 fixedly connected to the bottom portions of the blocking fence mechanism 2 (the static electricity releasing belts 4 are arranged along the periphery of the blocking fence mechanism 2). The static electricity releasing belts 4 are dragged on the ground. A plurality of static electricity releasing metal wires 41 are fixedly connected to the static electricity releasing belts 4. The static electricity releasing metal wires 41 are in contact with the ground.

[0057] During work, the static electricity on the fence is released through the static electricity releasing belts 4. The purpose of this mode is that the fence near the working area of the working equipment is more likely to accumulate electric charges. The static electricity is released through this mode. On the one hand, it is convenient for personnel to use, such as avoiding static electricity injury during the opening of the passage. On the other hand, the static electricity on the fence is released to avoid the attachment of dust in the air to the fence.

[0058] Of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
